Abstract/Contents: | "The dynamics of autumn color changes in four zoysiagrass accessions was analyzed by Sigmascan Pro 5.0 image analysis software using the photos of individual plants taken at intervals by a digital camera. The appropriate settings for selecting the green pixels were hue (H) 32-107, saturation level (S) 10-100, and for yellow pixels was H 10-32. The ranking order of the four accessions for dormancy date (from early to late) was Z. japonica cv. Liaoning, H2 strain, cv. Qingdao and Z. japonica var. pollida Nakai ex Honda cv. Jiaodong. It was concluded that there was a correlation between the date of autumn dormancy and the latitude of origin of the four accessions. Compared with traditional visual rating, the advantages of digital image analysis are greater repeatability and more accuracy." |
